Read the Amplifier class notes.
For the amplifier circuit shown, RS = 47 kΩ, and RL = 470 Ω.
For amp 1: Ri1 = 10 kΩ, A1= 25, Ro1 = 6.8 kΩ.
For amp 2: Ri2 = 1.2 kΩ, A2= 15, Ro2 = 1.8 kΩ.
For amp 3: Ri3 = 5.6 kΩ, A3= 5, Ro3 = 8.2 kΩ.
For amp 4: Ri4 = 8.2 kΩ, A4= 5, Ro4 = 680 Ω.

Find the gain, G = vo/vi.
